Definitions

  • the invention relates to a spirit level according to the preamble of claim 1.
  • the basic design of the spirit level according to the invention is a measuring instrument with which the horizontal or the vertically inclined position of a flat surface is checked. For this purpose, a bar of relatively great length is provided. This is necessary in order to record the area to be tested on a sufficiently large surface if the beam with its contact surface is to be placed on a surface that is to be weighed out horizontally or if a vertically rising contact surface is to be balanced vertically.
  • Dragonflies are used to weigh the spirit level according to the invention, i.e. an air bubble enclosed in a tube, which mostly plays in a defined axis under a cover sheet divided by a scale. The air bubbles adjust according to the angle of inclination of the surface to be tested.
  • Such spirit levels are used, among other things. used where it is important to determine an exact horizontal or vertical reference line regardless of the room system or an existing base. For example, When wallpapering room walls that are not exactly perpendicular to each other and to the floor, use the spirit level to determine an exactly vertical marking line before gluing the first strip. When building a building, masonry layers are checked individually for their horizontal course.
  • the invention is based on a previously known spirit level of this type (German utility model 75 04 115).
  • the bar is designed as a housing in which a light transmitter is installed together with an accumulator serving to supply it with power.
  • the light transmitter consists of a lamp, which can be operated with a switch and interacts with light openings of the dragonflies to illuminate them under unfavorable external conditions.
  • hose scales which consist of a transparent, water-filled hose, which is bent in a U-shape.
  • the minisks of the water columns in the U-legs are on the same level according to the principle of the communicating tubes.
  • at least two workers are always required to operate such spirit levels.
  • a spirit level which is also short, but has a built-in laser beam transmitter, which allows an extension in the horizontal and in the vertical when weighing a base.
  • this spirit level can only be used together with a tripod if reliable measurements are required.
  • the tripod has a rotatable tripod head, on which the spirit level is attached with the help of grooves left in its beam. This creates a level, which must be set up by adjusting the vials installed in the beams (CH-A 663 467). The invention is based on this spirit level.
  • spirit levels are also known, which, however, are only suitable for measuring angles, which include a base with the horizontal and which therefore do not have an extension device for the horizontal or the vertical (WO-A 88/04415).
  • the invention is based on the object of designing a spirit level of the type mentioned at the outset in such a way that error-free measurements even over larger distances are possible in a simple manner and these can generally also be carried out by one person.
  • the spirit level according to the invention can be used like a previously known spirit level, which has been described in the introduction. In this way, horizontal or inclined surfaces can be balanced along the length of the bar.
  • the laser transmitter is switched on, however, the laser beam emerging from the end face of the housing can serve as an extension of the contact or mounting surface because it runs parallel to the longitudinal direction of the beam.
  • the laser beam itself or its point of light hitting a certain distance from the new spirit level can be marked on a rising or horizontal surface.
  • the new spirit level has a protractor.
  • the protractor shows every tilt of the housing according to the degree of angle in the measuring plane. It can therefore also be used to measure the horizontal or vertical without the dragonflies or any inclined planes or lines or to transmit them over long distances.
  • the spirit level according to the invention is generally designated (1). It has a bar (2) which forms a housing (3) which is rectangular in cross section and rectangular according to the exemplary embodiment shown.
  • the bottom (4) of the housing (3) which of the lower cross-sectional edge (5) and the subsequent lower longitudinal edges (6 or 7) is limited, forms a mounting surface (8) which is used for the horizontal weighing of a base.
  • a dragonfly (14) is located on the housing surface (11) opposite and parallel to it.
  • the housing consists of an upper U-shaped housing part (25) with which a base plate (26) is screwed (Fig. 4), the outside of which forms the mounting surface (8).
  • the base plate is itself U-shaped and therefore has longitudinal legs (27) which are used for screwing.
  • the web (28) connecting the longitudinal legs (27) carries an insulating plate (29) which is fastened to the leg (28) of the base plate by means of insulating clamps (30, 31).
  • the tubular housing (34) of a laser transmitter is fastened on the insulating plate (29) in such a way that when it is installed in the housing (3), the laser beam which emerges at (35) parallel to the mounting and contact surface (8 or 9) in the longitudinal direction of the spirit level through the housing (3) (Fig. 5).
  • the beam of coherent light emitted by the laser transmitter (34) exits through an opening (36) on the end face (17) of the housing (3).
  • a set of rod-shaped batteries (37) is built on the leg (28).
  • the wiring of the batteries which is shown at (38), runs to a luster terminal (39), which in turn connects the electrical power source formed by the batteries with an on and off switch, not shown.
  • the wiring (39) leads to the laser transmitter (34).
  • a protractor (41) is removably attached to the housing (3) as an accessory.
  • the protractor has a movable bar (42) which is provided with a measuring line which adjusts itself over the circular scale (43) divided into angular degrees according to the inclination of the housing (3).
  • the exact angle can be determined using a vernier scale (44).
  • the protractor is installed in a housing (45) which is designed as a shaped body.
  • This body has an eyelet (46) with which the housing (3) can be held and tilted when the protractor (41) is attached. It also has a dovetail-shaped guide (47) for a U-profile (48), which is attached to the top (18) of the housing (3).
  • the opening of the housing which is denoted by (36) and from which the laser beam emerges, is located directly at the front end of the guide (48), the vial (14) being arranged at the rear end of the housing (3).
  • the other dragonflies are not shown.
  • a plate (59) (FIG. 2) is expediently provided, which is provided with a round perforation (60) which is covered with a cross hair (61).
  • the crosshairs are aligned with the center of the light spot (63) appearing from the laser beam on the rising surface (62) by hand (64).
  • a pin (65) With the help of a pin (65), the bearing or support surface (8, 9) can then be transferred to the light spot.
  • tiles (67) are to be attached to a wall surface (66), the joints (68) of which run horizontally.
  • the spirit level according to the invention according to the embodiment of FIG. 3 is based on that of the upper Tile layer (69) formed underlay (70) with its contact surface.
  • the laser beam (79) marks the extension of the base (70) so that the tiles that are still missing can be precisely aligned using the laser beam (79).
  • the spirit level (1) serves to fix the pitched roof (71) on a gable wall (72) of a building.
  • the laser beam (79) is used to align the artificial stones arranged at the ends of the masonry in the gable (72).
  • FIG. 7 shows the details of a measurement of a height point (73) on a rising building wall (74), which can be done with the aid of the plate (59) according to FIG. 2 described above.
  • the spirit level (1) is placed with its contact surface (9) on the subsequent rising wall (75) and the height of the laser beam (79) is measured.
  • a pipeline consisting of individual pipes (76 to 78) built in front of one another is set up on the slope using the spirit level (1) according to the invention.
  • the pipe (76) is already on the right slope.
  • the spirit level according to the invention with its contact surface is placed on the pipe (76), and the following pipes (77, 78) are laid using the laser beam (79).
  • the spirit level (1) according to the invention is mounted via an adapter (80) of a tilting device (81) of a stand (82). It can be set up with the aid of the tilting device (81) in the angle of 45 shown. If the horizontal and (x) designated distance of the adapter (81) from the wall (83) of a building (84) is known and the laser beam (79) hits the upper edge (85) of the flat roof (86) of the building (84), the height of the building can be determined on the basis of a simple arithmetic operation.
  • the adapter together with the stand (82) is used to measure height points (87) on measuring staffs (88, 89) in the field. This enables surface or height leveling.
  • the upper level (90) of a row of bars (91) is transferred to a measuring staff (92) by placing the spirit level (1) according to the invention on the top of the bars (51) so that the laser beam ( 79) extends the level (90) to the measuring stick (92).
  • the level (90) of the row of bars (91) is at the desired height.
  • the laser beam (79) is divided into two coherent light beams (79a, 79b) at right angles to one another.
  • the right angle can be measured with the help of the spirit level (1), which the neighboring, rising building walls have to enclose.
